The virus was also found present on the floor of the ICU unit in a hospital in Wuhan, China and on the soles of healthcare professionals, according to the study, which was conducted from Feb. 19 to March 2, 2020.

"In addition, as medical staff walk around the ward, the virus can be tracked all over the floor, as indicated by the 100 [percent] rate of positivity from the floor in the pharmacy, where there were no patients," researchers wrote in the study. "Furthermore, half of the samples from the soles of the ICU medical staff shoes tested positive. Therefore, the soles of medical staff shoes might function as carriers. The 3 weak positive results from the floor of dressing room 4 might also arise from these carriers. We highly recommend that persons disinfect shoe soles before walking out of wards containing COVID-19 patients."

Separate research that was published in March warned that droplets of the novel coronavirus could travel as far as 27 feet.

That study, conducted by researchers at MIT, raised eyebrows in the medical community, including Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, who urged caution on its findings.

“This could really be terribly misleading,” Fauci said at a March 31 White House press briefing, adding that it would apply only to people with extremely strong sneezes.

As of Monday morning, more than 1.86 million coronavirus cases have been diagnosed worldwide, including more than 557,000 in the U.S., the most impacted country on the planet.
